The polynomial for the VAN CRC is
x15 + x11 + x10 + x9 + x8 + x7 + x4 + x3 + x^2
To translate it to a hexadecimal poly value, you will need to take a 15 bit value and write a one in each interesting bit position.
The 15 bits are numbered from 14 to 0 . The leftmost (MSB) bit represents x14 (x15 is implicit) and the rightmost x^0 (which must always be set in any CRC poly, so it’s often not mentioned in the formula).
The result is:
000111110011101
or
0xF9D
